I'm not sure where you are located, but there is a product called Fiber n' Cotton that was developed by one of the people behind Fiber Freaks. I have never used it, but it seems to be similar to the cotton blend version of FF.

I like FF for RDTAs, but I use cotton on pretty much everything else. I don't notice the break-in period most people speak of, I often wonder if it's style of wicking issue. It may also be doing it wrong, so who knows (?)
